    Abstract: The present invention provides a simple method for introducing magnetic particles into a polymer for further preparing a magnetic polymer, the method using the capability of polymer to absorb Fe3+ and other divalent metal ions M2+, adding alkali immediately each time after absorbing Fe3+ or M2+, thereby generating hydrated oxide of the Fe3+ and hydrated oxide of the divalent metal ions in sequence inside the polymer, and then heating, so that the hydrated oxide of the Fe3+ and the hydrated oxide of the divalent metal ions are transformed into magnetic particles MFexOy, where M may be Fe2+, Zn2+, Mg2+, Cu2+, Ca2+, Ba2+, Sr2+, Ni2+, Co2+, Mn2+ and the like, and x=1.0˜2.0; y=3.0˜4.0. Compared with the prior art method, the present one is simpler, wider in application, and more operable.

    Abstract: Polymeric binder blended from thermoplastic and uncured elastomer binds magnetizable particulate in segmentally magnetizable materials used for encoder targets used in encoders and assemblies where encoders determine rate of motion. The polymeric binder has a dynamic mechanical thermal analyzer tangent delta value (ASTM E 1640-94) not greater than 0.1 at a temperature not less than the liquefaction supra point temperature of the thermoplastic when cured with radiation (preferably electron beam radiation) prior to being blended with either the magnetizable particulate or with other filler materials. The binder effects encoder targets evidencing robustness to thermal or chemical agent stress. Pre-cured blends of magnetizable particulate in the binder evidence good extrusion (pultrusion) performance.

    Abstract: A method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof. A colored gum material layer is paved on a surface of the rubber magnet. A surfactant is added into the colored gum material layer. An identical surfactant or a surfactant with very close polarity is added into the material of the rubber magnet, whereby the surfaces of the gum material layer and the rubber magnet can tightly adhere to each other without easy peeling. In addition, antiscaling agent, wetting/spreading agent and defoaming agent are added into the gum material layer to fully wet the color and uniformly spread the color over the gum material so as to enhance the evenness of the color.
